The Market™ is perhaps going after higher margins. If you can charge $200 instead of $100 for a widget, why wouldn't you?

Ideally at some point someone will see the margins and be motivated to go after some of it and offer things for $190, but the ROI on upfront fab costs given market risks may not be high enough for the business uncertainly that needs to be taken (boom-bust cycles).

No participant in The Market is obligated to "cater" to demand if they do not think the juice is worth the squeeze.
